Title: Liquid crystal element and liquid crystal device having this liquid crystal element
Inventor: MORI HIDEO
IPC: G02F1/133
Filed: 1998-08-21
Abstract: PROBLEM TO BE SOLVED: To widen a driving margin of a liquid crystal panel of a simple matrix type. SOLUTION: An inter-pixel reset pulse 7 is impressed to a scanning electrode to reset ferroelectric liquid crystals to a white state at the time of driving the liquid crystal panel. Next, this white state is maintained by impressing a reset pulse 8a of a scanning signal 8 and further a writing pulse 8b and an auxiliary pulse 8c are successively impressed thereto. Then, the growth of the domain (the domain disagreeing with the domain of the pixel region) from the region outside the pixel may be suppressed and eventually, the adequate range a writing pulse width ΔT (the range of the writing pulse width ΔT at which good image quality may be achieved) may be widened. The driving margin may thus be widened.

Abstract: PROBLEM TO BE SOLVED: To attain the automatic steering of a vehicle, regardless of the lane markers provided on a road surface by setting a traveling course based on the obstacle detection signals, vehicle position signals or the like, deciding a target traveling track, based on the set traveling course and running on the target traveling track. SOLUTION: Traveling instructions are decided in a traveling instruction process 23 for maintaining or changing the lanes, based on the information on the obstacles preceding a vehicle which are obtained by a laser radar 10 and the road information or the traffic information on a prescribed distance preceding the vehicle which are received from a communication device 15. When the traveling instructions are decided in the process 23, the more information on the traveling instructions are extracted and a point string showing a traveling course is set in a target point string extraction process 24. Based on this point string, a target traveling track is decided. A total plan ECU 13 transmits the vehicle steering signals obtained based on the target traveling track to a vehicle control ECU 22.  The ECU 22 performs the automatic steering of the vehicle, based on the vehicle steering signals.

Title: Manufacture of semiconductor photodetector
Inventor: ISHIHARA HISAHIRO
IPC: H01L31/10
Filed: 1986-10-03
Abstract: PURPOSE:To easily obtain a buried semiconductor photodetector having desirable flatness while prevening edte growth, by forming a groove in a semi-insulating semiconductor substrate before providing an insulating film all over the surface of the substrate: removing the insulating film from a specific region in the groove and growing crystals on the exposed specific region of the substrate to provide a light absorbing layer. CONSTITUTION:A groove is formed by etching a specific region of a semi-insulating substrate 1. An insulating film 3 is then formed to cover all over the surface of the substrate and the insulation film 3 is removed from the groove to expose the surface of the specific region of the substrate 1. Crystals are grown selectively on the exposed surface of the specific substrate region to form either a multilayer structure including a light absorbing layer 5 or a single light absorbing layer. For example, a semi- insulating InP substrate 1 is etched to form a recessed groove. After an insulating film 3 is formed to cover all over the surface, the insulating film is removed from the specific region in the recess. A multilayer structure is formed on the exposed specific region of the InP substrate 1 by depositing an N<->-INP buffer layer 4, an N<->-InGaAs light absorbing layer 5 and N-INP window layer 6 sequentially by means of the vapor phase growth process. Finally, Be<+> ions are implanted and annealed to form a P<+> region 7, so that a PN junction is obtained.
